Your heating system is far more than a luxury during the winter, when temperatures drop far below freezing. Without a reliable furnace or boiler, your home will soon resemble an icebox, which creates a health and safety risk above and beyond the comfort of your family. If you experience any kind of heating problem this winter, you should turn off the system and call in a repair technician immediately.
It’s also important to note that you should never attempt to diagnose or repair a faulty heating system yourself. Doing so requires proper training and licensing, and without those things, even the most enterprising layman will likely end up doing more harm than good. It’s enough to simply note that your system is having trouble—and anything that doesn’t correspond to the system’s normal functioning means trouble—then call in a professional to help.
